I agree with Wislim... One thing to add that did wonders for my game.... Do not steal pots on the button just because you the opportunity presents itself. I say if you have the kind of hand you could live with if you got called and knocked out or crippled, thats a stealing hand.
So the point is to semi-steal
hands late in a tourny. I played a lot when iwas in college and i got very god at getting close to money but always got knocked out when it counted the most. Then i stopped cold card stealing and got over the hump. I only steal with button with an actual hand which is not really stealing, i want a call.
I steal in the next seat from the button because it s alot more believeable, since there is steal the button in the hand. i establish a really mouse type image at the table and then defend my blinds and make these kinds of steals. I don't get alot of reasistance and i usually finish in the money or win.I play according to the situation, not the cards. I do not play only big pairs because you will just get your stack binded away. Hope that helps.
